【摘要】:考慮二次特征值反問題的廣義中心對稱解(廣義反中心對稱解)及其最佳逼近問題,應(yīng)用矩陣的正交投影方法,給出矩陣方程AX+BY+CZ=0的解及其最佳逼近問題.利用廣義中心對稱矩陣(廣義反中心對稱矩陣)的性質(zhì)導(dǎo)出了該問題有廣義中心對稱解(廣義反中心對稱解)的條件及有解情況下的通解表達(dá)式,并證明了最佳逼近問題解的存在性與唯一性,得到了最佳逼近解的表達(dá)式.
[Abstract]:In this paper, we consider the generalized centrosymmetric solution (generalized anti-centrosymmetric solution) and its best approximation problem of inverse quadratic eigenvalue problem. By using the orthogonal projection method of matrix, we give the solution of matrix equation AX BY CZ=0 and its best approximation problem. By using the properties of generalized centrosymmetric matrix (generalized anti-centrosymmetric matrix), the conditions for the problem with generalized centrosymmetric solution (generalized anti-centrosymmetric solution) and the general solution expression for the problem with solutions are derived. The existence and uniqueness of the solution of the best approximation problem are proved, and the expression of the best approximation solution is obtained.
